I read here http://forums.freebsd.org/showthread.php?t=28703 and here viewtopic.php?f=66&t=3823&p=19671&hilit ... and#p19671 I might need to use some form of zpool online -e command to get zpool to autoexpand once all member disks are larger than smallest member disk used when originally creating zpool. I also read elsewhere (serveral places) that normally you only need to export then import pool with autoexpand=on enable to get additional space available. I have zpool in use and don't want to bring down all systems accessing it as it hosts NFS export with lots of DEV VMware virtual machines on it.

What is recommended way to autoexpend while in use safely, if there is a way? Prefer answers from those who have done so already. Thank you.

SOLVED! I finally just tried the zpool online -e poolname device0 device1 ... devicen command like so (specific pool and devices names are mine, probably not anyone elses):
Command took a few seconds to run but completed and now I have the additional space. This did not impact the VMware virtual machines running the NFS datastore on that pool. This is a RAIDZ2 pool in case anyone cares.
